ASTM A789 is the Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Tubing for General Service.

ASTM A790 is the Standard Specification for Seamless and Welded Ferritic/Austenitic Stainless Steel Pipe.


ASTM A789 and ASTM A790 Duplex stainless steel pipe is typically manufactured using the seamless or welded process. For seamless pipes, a solid billet of the material is heated and then passed through a piercing rod to create a hollow tube. The tube is then rolled to the desired thickness and cut to length. For welded pipes, the material is first formed into a flat sheet. The sheet is then rolled into a tube shape and welded along the longitudinal seam. The welded pipe is then heat treated to remove any residual stresses and to improve its mechanical properties.
